Frédéric Lécaille d95ea2897e MINOR: log: Add "sample" new keyword to "log" lines. ... This patch implements the parsing of "sample" new optional keyword for "log" lines to be able to sample and balance the load of log messages between serveral log destinations declared by "log" lines. This keyword must be followed by a list of comma seperated ranges of indexes numbered from 1 to define the samples to be used to balance the load of logs to send. This "sample" keyword must be used on "log" lines obviously before the remaining optional ones without keyword. The list of ranges must be followed by a colon character to separate it from the log sampling size. With such following configuration declarations: log stderr local0 log 127.0.0.1:10001 sample 2-3,8-11:11 local0 log 127.0.0.2:10002 sample 5:5 local0 in addition to being sent to stderr, about the second "log" line, every 11 logs the logs #2 up to #3 would be sent to 127.0.0.1:10001, then #8 up tp #11 four logs would be sent to the same log server and so on periodically. Logs would be sent to 127.0.0.2:100002 every 5 logs. It is also possible to define the size of the sample with a value different of the maximum of the high limits of the ranges, for instance as follows: log 127.0.0.1:10001 sample 2-3,8-11:15 local0 as before the two logs #2 and #3 would be sent to 127.0.0.1:10001, then #8 up tp #11 logs, but in this case here, this would be done periodically every 15 messages. Also note that the ranges must not overlap each others. This is to ease the way the logs are periodically sent.		2019-04-30 09:25:09 +02:00
